The rate at which an electrical device converts energy from one form to another?
The rate of energy conversion - not just electrical energy, but any type of energy - is called POWER. The SI unit is the watt, which is equal to joules per second.
The power of a light bulb that converts electrical energy at a rate of one hundred joules per second is?
1 joule is the energy equal to 1 watt for 1 second.100 joules = 100w for 1 second.A 100 watt light bulb converts 100 joules of electrical energy into heat and light every second.Only about 1% of this is useful light, the rest is wasted as heat.AnswerPower is defined as the rate of doing work. As work is expressed in joules (J), it follows that power is measured in joules per second (J/s) -however, in SI, this is given a special name: the watt (W).So one joule per second is exactly equivalent to one watt. Therefore, 100 J/s is exactly equivalent to 100 W.
What do you call to the rate at which an appliance converts electrical energy into other forms of energy?
The rate of conversion of any type of energy is called power. In the international system (SI), the unit for energy is the joule; the unit for power is the watt, which is equal to joules/second.
How many Joules of electrical energy does a 100 Watt light bulb consume from the electrical supply in 2 seconds?
Watt means joules/second. It refers to the amount of energy a device uses, in this case. Multiply the power (in watts) by the time (in seconds) to get the energy (in joules).
What is the rate at which electrical current is converted to another form of energy?
The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.The rate of energy transfer or transformation is mesured in joules / second, also known as watts.

How many joules of light energy are in 1440 watts of electrical energy?
A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts. Watts means joules per second (joules / second), or equivalently, joules is watts times seconds.A joule is a joule, whether it be electrical energy or light energy - although commonly, lamps are not 100% efficient.On the other hand, you can't convert joules directly to watts.

What is the between work and power?
Work is how much energy is transferred, measured in Joules. Power is how fast or slow the work is transfered, measured in Joules per second. One joule per second is called one Watt of power. This meams a 60 Watt light bulb converts 60 joules of electrical energy into roughly 15 joules of light and 45 Joules of heat every second its switched on for.

Is the length of time an electrical load is on proportional to power or energy?
Power (watts) is amperes times voltage, or joules per second. Energy is joules, or watt-seconds. The length of time an electrical load is on is proportional to energy, not power.

How are electrical power and electrical energy related?
Power is always the time-rate of energy, i.e. the rate of change (or transfer) of energy with respect to time.If Energy is measured in Joules, then one Joule being transferred in one second is equal to one Watt of power.Electrical power is the time rate of change of electrical energy, P=dE/dt.Power = energy / timeIt usually referst to some type of energy transfer. In SI units:Watts = joules / second
How does watt and joule relate?
The Joule is a unit of energy, while the Watt is a unit of power. Joule is the alternate name for a Newton-meter of energy, and Watt is the alternate name for a Newton-meter per second of power. This means that one Watt is one Joule per second; a 100-Watt light bulb converts 100 Joules of electrical energy every second into heat energy and light energy.
